    Question Yet More Capacitors

    Anyone else have any experience with these puppies?

    SoniCaps at GR-Research

    Sonic Craft

    Try this

    The guys at AudioAsylum seem to like them and compare them favorably with Auricaps, etc, etc

    http://db.audioasylum.com/cgi/m.mpl?...ps&r=&session=

    Having ordered a pair of 3.0 uf Sonicaps for my L-112 X-overs, to parallel the C1 Midrange cap and bring it up to the 16.5 uF value of the vaunted 3113b X-over (Thanks, Giskard for the excellent info), it's going to be hard to tell as this is going to be a whole new X-over for the L-150's.

    Giskard, did you ever get a chance to try the Sonicaps? Anyone else?

    Good product

    I tried them out on the L-112 X-over. They were expensive. I ended up paying about $12 apiece for them, including shipping (they were well packed). The construction is top notch, good appearance, extra long leads. They don't look cheap. I'm glad I went this route, because the L-112 x-over is super well made, almost pro quality (compared to my L-110 X-overs with cold solder joints, sloppy but workable construction, et-al).

    While I never heard the X-overs without the new caps, there certainly wasn't any degradation of sound, because I was really just reformulating the L-112 into a 3113B crossover, making the 13uf C1 into a 16 uf cap. I'm happy with the results.

    A nice review of some quality capacitors, and a few surprises.

    Yep,,, - There were some very interesting opinions expressed.

    I'll repost this url which has a more simplistic but nice "overview on many Namebrand Caps" .

    I always enjoy a reviewers' comments that include "DIY'ers spend ridiculous amounts of money for voodoo caps, " or " Some well-regarded brands do sell exactly the sort of flooby dust that the preceding discussion attempts to debunk."

    It's always healthy to get a different perspective.

    Also, here's a site that puts "capacitors/dielectrics through the oscilloscope" . It's nice to see some science,actually applied to this extremely "nuanced" area.


    There: Now some opinions from 2 quite articulate "devils-advocates" have been included in the discussion.

    That second article is excellent. The distortion is much easier to see than I would have expected. I gotta get rid of those NPEs.

    "Even more detail and seperation can be created by bypassing them with an MKP1837 (a good tweak for any capacitor!)"

    If anyone cares, now would be the time to aquire them and try them in the Project May networks... I'll leave it up to someone else to purchase them and send them to Mr. Widget in San Francisco.

    Thanks Ian and Earl for those interesting articles. I agree that caps do change the sound, but frequently I can't say Yeah baby that's the one!

    Typically it is more of a well, it's different. Of course I am not talking about 50 cent NPEs.

    A guy called Klaus on the diyaudio.com forums has recently tried the 1837 using Panasonic FC electros and says they make the right kind of difference. He also tried Wina's and other small value capacitors and also recommends cascading Mundorf Supreme 0.1 uf in some applications.

    The thing is to get the right combination of characteristics that will not react badly with the main capacitors. That said imho you need a reasonable good main capacitor to start with.


    I don't think any of this is new stuff but is certainly worth trying with the Project.

    Yeah, my only hesitation is putting a metallized 'anything' in parallel with the Sonicaps. The whole point of using them is to get away from metallized dielectrics. A top quality film and foil bypass maybe, but a metallized polypropylene? Anyway, you guys can try whatever comes to mind. We might all be surprised!
